Magnetic excitations in single-crystals of LaFeAsO
We aim to determine the magnetic excitation spectrum in single-crystals of the parent LaFeAsO compound and thereby address some basic issues concerning the nature of the... -
Study of spin wave and crystal field effect in R2RuO5 (R = Pr, Nd, Tb
R2RuO5 (R = Pr, Nd, Sm, Gd, Tb) are known to exhibit interesting physical properties. They all show magnetic ordering between 8 ¿ 24 K. They also show large Sommerfeld... -
Magnetic Excitations of a New Heisenberg-Kitaev Quantum Spin Ice Candidate
We propose to measure the magnetic excitation spectrum of the potential Kitaev spin liquid compound Li2RhO3. Moderate spin orbit coupling in the Rh4+ ion is expected to results... -
Magnetic excitation in triangular latticce antiferromagnet alpha-CaCr2O4
The triangular Heisenberg antiferromagnet is the classic example of the frustrated magnet, here the ground state forms a non-collinear 120° structure. A number of different... -
Inelastic neutron scattering study on double perovskite Sr2TIrO6 (T = Ca, Sc,...
Recent observation of AFM transition at 1.3 K in Sr2YIrO6 with Ir in 5+ valence state has motivated research interests in the double perovskite Sr2TIrO6. Usually Ir5+ with a... -
Spin excitations in LiFeAs, a stoichiometric ferropnictide superconductor at ...
We propose to measure the powder-averaged spin excitation spectrum of LiFeAs, a new member of the ferropnictide family of superconductors. This compound is special because it is... -
Spin dynamics in a honeycomb antiferromagnet with strong spin-orbit coupling
This proposal is part of our research programme to explore novel ground states stabilized by frustrated interactions in quantum magnets. Here we plan to measure the spin... -
Neutron Spin resonance in the Fe-based silicide superconductor LaFeSiH
The iron-based superconductors (Fe-SC) are one of the most active and challenging topics in condensed matter physics. Very recently some of us (F. Bernardini et al.) have...
